We had a 4 days break in Marrakech in March. We booked a private transfer from Marrakech airport (about 6 miles from the old city/medina) to our hotel, both ways. All went very smoothly. We checked how much a standard city taxi would be (they are regulated at this airport) and the Holiday Extras car was a few pounds more but much cheaper than a hotel car. Our first time there so we valued the guarantee and contact numbers and English-speaking contact. For the return trip (no vehicles could get down the narrow alleys to our hotel) the hotel reception phoned and checked our driver was ready for us (he was waiting at the end of the alley already) and sent a porter with us to ensure we got the right vehicle. We could have done this on our own but why refuse? He dropped us as close as he could to the check-in desks we needed. Only query was arriving from Birmingham - HolidayTaxis are immediately outside the Arrivals Hall rather than inside it, and an airport jobsworth on the door tries really hard to prevent people re-entering to get luggage and wife! If you separate to look for your name card keep in sight of each other - it's a big space.
